Demonstrates how to load a PEM key into the Chilkat RSA object. PHP Extension

<?php

include("chilkat.php");

$success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$rsa = new CkRsa();

// First demonstrate importing a PEM public key:
$publicKeyPem = 'PEM public-key data goes here';
$pubkey = new CkPublicKey();

$success = $pubkey->LoadFromString($publicKeyPem);
if ($success == false) {
    print $pubkey->lastErrorText() . "\n";
    exit;
}

$success = $rsa->UsePublicKey($pubkey);
if ($success == false) {
    print $rsa->lastErrorText() . "\n";
    exit;
}

// Demonstrate importing a PEM private key:
$privateKeyPem = 'PEM private-key data goes here';
$privkey = new CkPrivateKey();

// If the private key PEM is protected with a password, then 
// call LoadEncryptedPem.  Otherwise call LoadPem.
$success = $privkey->LoadPem($privateKeyPem);
if ($success == false) {
    print $privkey->lastErrorText() . "\n";
    exit;

$success = $rsa->UsePrivateKey($privkey);
